Neuralarchitecture search (NAS) aims to produce the optimal sparse solution from a high-dimensional space spanned by all candidate connections. Current gradient-based NAS methods commonly ignore the constraint of sparsity in the search phase, but project the optimized solution onto a sparse one by post-processing. As a result, the dense super-net for search is inefficient to train and has a gap with the projected architecture for evaluation. In this paper, we formulate neural architecture search as a sparse coding problem. We perform the differentiable search on a compressed lower-dimensional space that has the same validation loss as the original sparse solution space, and recover an architecture by solving the sparse coding problem. The differentiable search and architecture recovery are optimized in an alternate manner. By doing so, our network for search at each update satisfies the sparsity constraint and is efficient to train. In order to also eliminate the depth and width gap between the network in search and the target-net in evaluation, we further propose a method to search and evaluate in one stage under the target-net settings. When training finishes, architecture variables are absorbed into network weights. Thus we get the searched architecture and optimized parameters in a single run. In experiments, our two-stage method on CIFAR-10 requires only 0.05 GPU-day for search. Our one-stage method produces state-of-the-art performances on both CIFAR-10 and ImageNet at the cost of only evaluation time.

This is my first time posting on this forum. I just want to say first of all how much I appreciate all of the good information being posted on this forum. I look forward to contributing more here in the future.
This is my first time programming a BMW vehicle. I have been doing a lot of reading about precautions and things to be aware of when programming BMWs. I thought that I was going to use ISTA P to program the car (per the bulletin), but when I finally got that software running, it said that the programming tasks for these cars (F series) should now be performed in ISTA +/ISTA D/ISTA 4.0 (whatever you call it). So, after some time getting that software to run properly, doing a complete vehicle identification, then clicking on the vehicle management tab, and then the software update tab, I have run into a snag and have a few questions that someone with more ISTA programming experience may be able to help me with:
Thank you so much to anyone who is able to help me with this and takes the time to respond. It seems like the learning curve for ISTA is kind of steep compared to other manufacturers, but I will get it eventually
Somebody needs to start screaming stop when BMW F and G chassis are attempted to be programmed j2534. My advice is don't do it unless you have a genuine icom. Using aftermarket tooling will also probably be a waste of time. Many times aftermarket tooling does not have the latest calibrations. Selective programming can also cause problems with F and G chassis cars.
Using ISTA once you enter the programming it will ask you if modules have been replaced - select No. You should get a option to exclude infotainment but otherwise you can not just update the DME. ISTA will determine a measure plan and you will accept it.
This is what I think OP clicked when trying to update the DME only before knowing all modules would be updated. Simple mistake, should just be able to create a new measures plan with that unchecked. Me wonders if you went through with the current measures plan and didn't even unplug the DME and just spammed the next key if it would just reprogram anyways and accomplish what he needs.
Thank you for your input. Unfortunately, there was never a point where ISTA asked me if modules had been replaced. I have run through the procedure 3 or 4 times to make sure something like this was not going on.
To make this software easy to use, our technicians have combined the knowledge in the book BMW ISTA P coding manual . In this book there is all the knowledge on how to repair, how to use BMW software in detail.
Depending on the model of vehicle that you repair to choose the most suitable software

Mr Brendan Smith, Co-Founder of CoderDojo Galway City, recently provided members of the Galway Branch of the Irish Science Teacher's Association (ISTA) with a 2-hour workshop on using Scratch software in an educational context.
This CoderDojo event was organised by Dr Veronica McCauley, Science Educator in the School of Education, NUI Galway. It gave science teachers the opportunity to try out the 'Scratch' coding software in a supportive and fun learning environment.
Founded in 1845, we've been inspiring students for over 175 years. University of Galway has earned international recognition as a research-led university with a commitment to top quality teaching.
